IMPROVEMENT'INI LOOM-PICKING artens;

We, HENRY A. WHITTEN and ELIJAH 1). Gone, both' oi- Holyoke, Hanipden county, Commonwealth of Massachusetts, have invented certain Improvements in Picker-Motions for Looms, of which the following is a specification.

' Nature and Objects of the Invention,- Onrinveution relates to that class of picker-motion in which the movement of the picker-stick is derived from a rocker, to whichit is attached at one end, the

, rocker being provided with teeth to mesh with a ratchet, upon which it oscillates.

By giving an inclination to-the ratehetpiece when the pulling-strap releases the picker-stall its own 'weight rocks it back.

llhe rocker has flanges that project on each side over the ratchet-piece, and prevent its being thrown oil the ratchet-piece by the motion of the lathe, while the ratchet and teeth to theroeker prevent its having any longitudinal play, and being drawn out of place either by the pulling-strap in one direction or by the weight of the picker-stick in the other. v v

' Our invention consists in making the ratehet pieee adjustable by bolting one end to the flanges of a collar, so that it is hinged on one bolt, while, by means of a set serew playing in a slot, the ratchet-piece can "be lowered to" any degree and secured. The collar passes over a stud attaoheddirectly to the lathe, and is clamped by a screw.

' A is the rocker, having the picker-stick B attached to. it at one side of the center, and having the flanges E E and teeth a a, &e.','which mesh with the teeth b 1:, See, on the ratchet-piece l); i

' L is the stud, attached tothe lathe, and upon which 1 is the belt which hinges the ratchet-piece to the collar; and v I O is the set-screw working in the'slot f, and for the purpose of regulating the inclination desired to be given to the ratchet-pieee 1). i

The rocker-is madeadjustable so that the degree of its inclination from the horizontal can be varied to cause the picker-staff to rock more or less fast to suit the requirements of the class of work upon the loom.

strueted and arranged substantially in the manner and for the purpose shown and described;
